I figured I'd made a suggestion that popped up in the depths of my mind. I would imagine it's not an easy one to implement, and since my coding know how is about zero I don't even know if it's possible... But I thought I'd put it out there in case it sparks something.

Comfort:

A new bar in addition to hunger and thirst. This bar would fill when your character gets to do something nice.

Ways this could work...

Commodity: This could be something like a particularly nice meal, or other pleasant commodity.

Slow Regeneration: Sitting in a warm place (where generator is running, or there is a nice warm fire going, or similar)

Activity: A pleasant activity, perhaps a visit to the doll house and a purchase of their services. This could possibly be done through the hud or through purchase of 'service' commodity, or similar.

______________________________

I first thought of calling it 'mood' but I realize that a lot of roleplayers wouldn't want their character's mood dictated to them.

Comfort could potentially affect the character's stats, abilities or resistances either positively or negatively.
